New gas pressure regulator doubled the gas pressure output. Will advise if this solved the problem. (Got some heat in the coils, but can't tell just yet on the cooling efficiency.)

Hmmm.. That would do it. If it doesn't get the 11" WC gas pressure it wouldn't heat
enough properly. ( it would still burn blue flame just not enough of it.)
Makes me wonder if someone had replaced the regulator with one off a gas grill?,
They operate at about half of the regular units. 4" WC on the two I had recently.(low flow)
Makes sense....
